Living fly maggot liquid protein leech culturing feed and preparation method thereof

Abstract

The present invention discloses a living fly maggot liquid protein leech culturing feed and a preparation method thereof. The feed comprises the following raw materials in parts by weight: living fly maggots 70-80 parts, blood meal 40-60 parts, corn germ meal 30-50 parts, dilute soybean milk 230-250 parts, heartleaf houttuynia herb extract 3-5 parts, shii-take powder 3-5 parts, curry sauce 2-3 parts, sea fish oil 0.4-0.6 part, honey 0.5-0.8 part, EM zymophyte fermentation liquid 2-3 parts, sucrose fatty acid ester 0.3-0.5 part, nisin 0.05-0.1 part, and rice washing water 200-230 parts. The living fly maggot liquid protein leech culturing feed is prepared by the five consecutive and orderly processes: homogenization, boiling, fermentation, thick liquid grinding, and sterilization. The feed is in a liquid state, is more palatable than solid feed, is very easy for the consumption of leeches, is rich in nutrition and unique in taste, strongly attracts leeches, can accelerate growth and development after the consumption by leeches, shortens culturing cycles, reduces diseases, and increases output.

Description

technical field [0001] The invention relates to the technical field of aquatic feed processing and preparation, in particular to a living fly maggot liquid protein leech breeding feed and a preparation method thereof. Background technique [0002] Leeches, commonly known as leeches, are cold-blooded annelids that move very quickly. They can swim like waves and migrate like inchworms. It can grow and reproduce in both the north and the south of our country. It mainly lives in reservoirs, ditches, paddy fields, lakes and swamps in fresh water. It is most abundant in ponds rich in organic matter or in non-polluted rivers. It enters the dormant hibernation period in the soil at 3°C, and stings will emerge at temperatures above 8°C from March to April of the following year. Leech is a traditional special medicinal aquatic animal in my country. Its dried products can be used as medicine after brewing. It has the effects of treating stroke, high blood pressure, clearing blood stas...

Problems solved by technology

With the application and improvement of modern biotechnology, the extraction and processing of hirudin and the clinical application of medicine, as well as the development, development and promotion of Chinese patent medicines, the demand for leeches is increasing year by year. However, the lack of wild leeches is far from enough To meet the huge supply demand in the market, artificial breeding is urgently needed to fill the huge supply gap in the market

Judging from the currently mastered leech breeding technology, the curren
